Materials in sport

Extracts from this document...


Materials in sport Ceramics are any inorganic non-metallic material. Examples of ceramics can be from table salt to clay (complex silicate) some scientists say that ceramics must also be crystalline. This means that the molecules of the material are arranged in a regular pattern. The materials that are inorganic non-metallic but do not have a crystalline structure are called amorphous. An everyday example of an amorphous material is glass. This ranges from glass in bottles to the high purity glass in optical fibres Some useful properties of ceramics are: high melting points, low density, high strength, stiffness, hardness, wear resistance, and corrosion resistance. Many ceramics are good electrical and thermal insulators. Certain ceramics have special properties. Some are magnetic or super conductors. Ceramics do have one major draw back; they are very brittle Traditional ceramics are materials such as clay, talc, and porcelain that make products like pottery, bricks and containers for food. Engineered ceramics are materials including silicon and aluminium nitride that make products such as sensors dental restoration and artificial bone implants. Metals Metals can be separated into two groups, these are pure metals and metal alloys, pure metals are single elements from the periodic table. Iron and copper are examples of pure metals. Metal alloys are a combination of more than one pure metal. ...read more.


A polymer/ceramic material will have a higher melting point than a polymer but be less brittle than a ceramic. Composites can also be natural materials such as wood as it contains cellulose fibres, Composites are divided into two categories, fibre reinforced composites and particle reinforced composites. Fibre reinforced composites can be made of metals ceramics glass or polymers. It is difficult to process fibre reinforced composites so they are generally expensive to buy. The carbon fibre in race bikes is an example of the fibre-reinforced composite. The bikes that use it are very expensive and only top-level athletes use them. Partial reinforced composites include ceramics glasses and metal particles like aluminium. The particles decrease the ductility of the material. The particles are also used to make cheaper composites. Swimming technology advances. Swimming has been around for a very long time. No one is completely sure when swimming first came around. Some people say the Romans invented swimming so that their soldiers could advance across deep lakes and rivers without needing bridges or wasting time walking around. Swimming was also used in India as a form of mediation but this was more floating than swimming. The English are considered the first modern society to develop swimming, as a sport and Swimming became a recognised sport by 1837. ...read more.


The Aquablade swimsuits contain slick, water repellent resin to make contrasting rough and smooth stripes on the suit. The principle behind the suit is that the two stripes generate a slow and a fast current causing vortexes to be formed when the two currents interact. As a result, the water stays closer to the body longer and hence there is less turbulence and dispersion of water around the swimmer allowing him to 'blade through the water'. The newest models of swimsuits is the Speedo body suit made with the patented Fastskin Fabric by Speedo for their line of Sharkskin swimsuits and the other is the Addidas Equipment bodysuit made out of a material resembling that of Speedo's. Made of super-stretch fabric, the Speedo suits fit the body snugly and compress the muscles of the swimmer which proves - according to Speedo - to be more efficient since muscles work in groups. Speedo has also created an anatomic/dynamic pattern where seams on the suits act like muscles and tendons as they stretch with overall hand and body movement. The new suit technology is very controversial and some people still believe that it does not help the swimmer and others believe it is unfair for some people to use the suits but not others. Either way the technology has advanced and due to new materials the equipment in sport will always continue to be modernised and made more effective. ...read more.

    The thickest material (carpet) was the most effective insulator, and the next thickest (bubble wrap) was the second most effective. This pattern is consistent throughout all of the materials, so in conclusion we know that the thickness of the material is the main factor that affects its effectiveness in reducing heat loss.

    This is due to the fact that ductile materials other than steel typically do not have a well defined yield point. For these materials the yield strength is typically defined by the 0.2% offset strain. The yield strength at 0.2% offset is determined by finding the intersection of the stress
